No matter how mature batteries become, they are a
maintenance problem. They eventually must be
replaced. Despite long life projections, it is
impossible to know if any individual battery will last
considering all of the factors that can degrade them.
6. Environmental
Lithium batteries are widely regarded as an
environmental problem. They are a potential fire
hazard and proper disposal can be a burden. In
addition, shipping of lithium batteries may be
restricted.
7. Style!
Backing up an SRAM with a battery is an old-
fashioned approach. In many cases, such modules are
the only through-hole component in sight. FRAM is
the latest memory technology and it is changing the
way systems are designed.
FRAM is nonvolatile and writes fast -- no battery
required.
